Protesters angry over Iran's ailing economy have conducted a sit-in at Tehran's Grand Bazaar. Security forces fired tear gas and dispersed demonstrators as the market shut down. The protests Tuesday come as Iran's rial currency fell to a record low. Activists say violence surrounding the protests has killed at least 36 people, with authorities detaining more than 1,200 others. Iran's Central Bank recently reduced subsidized exchange rates for dollars, likely leading to price hikes. Reformist President Masoud Pezeshkian warned the crisis might be moving beyond government control. The situation is likely to worsen as inflation and sanctions continue to impact the economy.
